I'm having problems trying to record from a sound card under
8.1-RELEASE. The last time I tried this was many releases ago,
possibly 4.x-RELEASE. Back then I would do something like "cat
/dev/dsp > file" but now when I try it I just end up with a 0 byte
file. I'm using a different sound card than before so maybe that
has something to do with it. Or possibly I just don't know which
device to use. Playing sounds using "cat file.wav > /dev/dsp0.0"
works fine, but I can't get recording to work. Does anyone have
any suggestions? Thanks.
